And over periods of millions of years, we also have geological activity raising landmasses.

Even faster than that, land is rising very fast in places previously glaciated. Unsurprisingly, taking a mile thick glacier weighs the land down a bit.

And sea levels change radically according to ice age cycles, by over 100 metres.

Do the residents of New York realize that their city is named after a place where men have cloth caps and whippets?

Should be new Keighley tbh!! 🤣🤣🤣

If coastal erosion is a yard a year in some places, how come the whole country hasn't fallen into the sea? At a yard a year it would take 1760 years for the coast to erode one mile, but if we believe scientists, the planet is 4.5 billions years old. Even in one million years the coast would have come inwards about 600 miles. That is practically all of Great Britain. In ten million years every continent on earth should have fallen into the sea.
And if you look at the watergate at Harlech castle, the sea is now about a mile away, but on the opposite side of the country, the Norfolk coastline is eroding at a steady rate.
Maybe the British Isles is heading towards America - ! :laugh:

Same on the Wirral (yes - ON the Wirral)
The beach around Parkgate used to be at the sea wall -Nelson docked there to load troops for some campaign or other

when I we a lad at very high tides you could see the grass moving with the waves and large areas of water

nowadays it is basically just scrub grassland - in some areas they graze sheep on it!
and West Kirby and Hoylake have been heading the same way for many years - only kept back by local activists but they are fighting a loosing battle
In the old days the sailing club at Hoylake was where they sailed from
when I was sailing there we sailed from a few miles up the coast - that was the 1980s

And the local mayor who couldn't spell called the surrounding area Neston instead of Nelson!

I have just made that up by the way 🙂

Oh really??
we couldn't tell!


for those that want to know Ness in a town name mean headland
so Neston means the Town near the headland

on old maps there used to be a headland nearby - but it has been washed away by tides etc

a lot of the changes to the area were caused when the course of the River Dee was changed to flow along the Welsh side rather than the Wirral side

in case anyone is still reading
I grew up round there - hence knowing stuff
(and Wikipedia helps!!!)

Two competing things there.

Continental drift is widening the Atlantic, but that might be overwhelmed by geological deposition in some localities.


That process of deposition works fastest in shallow seas, so will slow or stop once that coastal "growth" hits the edge of the continental shelf, where the seabed plunges to the abyssal plain.

Suppose the mid-atlantic riDge could grow and create a brand new continent. It would include regions such as Surtsey, Iceland and 'Azores'.

(And i used to think oxbow lakes were the peak of Geography)

Camber Castle in East Sussex was built as part of Henry VIII's coastal defences.

Within 100 years, the sea had receded so far that the coast was beyond the range of the cannons mounted on the castle ...

As a child of the 1940s & 50s I always listened to the shipping forecast and wondered what they were on about but…now I knows.
